5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine CAS 22276-95-5

Description

The occurrence of 5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine is closely related to a nitrile group, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine (CAS 22276-95-5) is a high-purity analytical reference standard with the molecular formula C6H3BrClN3 and a molecular weight of 232.47 g/mol.

The molecular framework of 5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine (C6H3BrClN3) is characterized by a nitrile group, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 5-Bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
